HE Textile Industry is one to which the Cooper Hewitt Lamp is peculiarly adapted. The above
rphotograph shows the weave shed in the worsted department of the Pacific Mills. One
200 watt Cooper Hewitt Lamp is placed over every five looms. This method was adopted after 10 years
use of Cooper Hewitt Lamps. Due to the restful green color of this light the eye is enabled to distinguish
the finest detail in the manipulation of cloth, with a total absence of eye strain.
